% Stenosis

Diameter
NOTE:
When you use diameter to calculate the %stenosis, always take
the measurement from a cross-sectional view of the vessel.
To calculate percent stenosis by diameter:
1. From the Generic Touch Panel, select
% Stenosis
.
2. Select
%sten(Diam)
.
The system displays an active caliper.
3. Make a distance measurement of the inner area of the blood
vessel.
The system displays an active caliper for the second
distance measurement.
4. Make a distance measurement of the outer area of the blood
vessel.
The system displays each distance measurement and the
% Stenosis in the Results Window.
For details on how to make a distance measurement, See
‘Distance measurement’ for more information..
NOTE:
For the diameter calculation, do NOT take a distance
measurement from a longitudinal view. This may lead to an
inaccurate assessment of % stenosis.
